Clamp-On Ground Resistance Testers
The Clamp-On Ground Resistance Testers measure ground rod and grid resistance without the use of auxiliary ground rods. Offer accurate readings from 0.01 to 1200Ω as well as ground leakage current from 1mA to 30Arms without disconnecting the rod under test.

3-Point Ground Resistance Testers
The AEMC 3-Point Ground Resistance Testers are available in both analog and digital models. These Fall-of-Potential testers are designed to reject high levels of noise and interference. Measurement ranges up to 1999Ω. Also available as a complete kit which includes leads, ground rods and carrying case.

4-Point Ground Resistance Testers
The AEMC 4-Point Ground Resistance Testers are ideal for both soil resistitivity and Fall-of-Potential testing. Models are available as battery powered or AC power cord. All models are available in complete kit form which includes leads, ground rods and carrying bag.

Multi-Function Ground Resistance Testers
The Model 6470 performs grounding resistance, earth coupling measurement, soil resistivity and bonding tests. The Model 6472 instrument is designed to measure Bond Resistance, Ground Resistance (with and without clamps), Soil Resistivity, Earth Coupling, Step & Touch Potential.
